All Sightmark magnifiers are compatible with Sightmark Ultra-Shot optics.
Magnifiers are designed to magnify the image already being produced from both an optic and the environment. Most optics on todays market are designed to co-witness with iron sights. This means that most optics are designed to have a similar height from the which they are mounted. While there are exceptions out there, most magnifiers should line up with most optics that will co-witness.
